But wait," you say, "I thought we took care of the environmental problems of air conditioning refrigerants a long time ago when we replaced ozone-depleting chlorofluorocarbons (CHC-12) with hydrofluorocarbons
In addition to their energy efficiency improvements, the new machines use carbon dioxide (CO2), a natural refrigerant, instead of hydrofluorocarbons
(HFCs), marking the first time that vending machines cooled by CO2 have been introduced in the United States.
Cognis BV and the Lubrizol Corporation (NYSE:LZ) announced today that they have concluded an agreement in which the two companies have cross-licensed their respective worldwide patent portfolios relating to lubricants for use with chlorine-free hydrofluorocarbon
The 5CP is a new product developed as a feedstock for the manufacture of hydrofluorocarbon
The refrigerants - Suva(R) 407C and Suva(R) 410A - are the leading hydrofluorocarbon
(HFC) products globally for air conditioning and heat pump applications, for which DuPont has patents in various countries, including China, India, Malaysia and Spain, among others.
As a result of the new marketing alliance, AlliedSignal has chosen to suspend development activity on its next generation solvent, HFC-356mcf, a hydrofluorocarbon
, according to Kevin M.
BULLETIN BOARD: INIS) announces it has been awarded a grant by the National Science Foundation (NSF) Small Business Innovation Research program to complete a Phase I investigation into the use of germanium tetrafluoride as a fluorinating agent for development of new and more efficient processes for production of hydrofluorocarbon
The European Commission also will speak to its Mobile Air- Conditioning Directive, which mandates the phaseout of hydrofluorocarbon
(HFC) R-134a beginning in 2011 for all new auto platforms.
He underlined the crucial importance of exploring alternatives so as to control climate-change-inducing hydrofluorocarbons
As the world counts down to the UN Climate Change Conference in Paris at the end of this month, the 197 parties to the Montreal Protocol on Substances that Deplete the Ozone Layer have agreed on a "Dubai Pathway" for controlling climate-change-inducing hydrofluorocarbons
19, 2015 /PRNewswire/ -- Demilec, one of North America's largest manufacturers of spray foam insulation and polyurea products, has announced that the company is phasing out hydrofluorocarbons
(HFCs) from its product lineup and is in development of its first hydrofluoroolefin (HFO)-blown spray foam.
Secretary-General Ban Ki-moon said Wednesday that a political commitment to manage hydrofluorocarbons
(HFCs) under the Montreal Protocol - in which it was agreed to phase out ozone-depleting chemicals - could be one of the biggest climate change victories in the lead-up to December's climate conference.
